Construction material is any material used for
construction purpose such as materials for
house building. Wood, cement, aggregates,
metals, bricks, concrete, clay are the most
common type of building material
used in c onstruction. The c hoice of these are
based on their cost effect iveness
for building projects.
Industrial resources (minerals) are geological
materials which are mined for their commercial
value, which are not fuel (fuel minerals or mineral
fuels) and are not sources of metals
(metallic minerals) but are used in the industries
based on their physical and/or chemical properties.
They are used in their natural state or
after beneficiation either as raw materials or as
additives in a wide range of applications.
Typical examples of industrial rocks and minerals
are limestone, clays, sand, gravel, diatomite, kaolin
bentonite, silica, barite, gypsum, and talc. Some
examples of applications for industrial minerals
are construction, ceramics, paints, electronics, filtrat
ion, plastics, glass, detergents and paper.
The evaluation of raw materials to determine
their suitability for use as industrial minerals
requires technical test-work, mineral
processing trials and end-product evaluation;
free to download evaluation manuals are
available for the following industrial minerals:
limestone, flak e
graphite, diatomite, kaolin, bentonite and
construction materials.
Every manufactured product contains materials
derived from minerals.
One of the most s ignificant characteristics of
chert is being brittle under load.
Plaster is obtained from gypsum rock that is
crushed and dehydrated
Porcelain is made with kaolin. It is t ransparent,
translucent, compact, acid-resistant and hard.
Travertine may be used in cladding and tiling.
Cement is a grey powder made from a mixture of
crushed and heated limestone, clay and gypsum.
Limestone is porous, off-white and used as
aggregate, pavements, cladding and tiling
materials.
Feldspars decompose to clay minerals.
Scoria is used as a suitable construction material
in light weight aggregate.
Basalt is suitable Aggregate sources.
Feldspar is used as a glazing layer in ceramic
industry.
Ceramic materials are made f rom fine grained earth
clay composed of aluminum silicates and other
substances.
Terrazzo is a mixture of gravel and white cement and
it's a very resistant material.
Silica sand is the main raw material in glass industry.
Cement is a grey powder made from a mi xture of
crushed and heated limestone, clay and gypsum.
Marble is a metamorphic rock, dense and resistant
to compression. It is cold to the touch and it has a
widely varied naturals colours. It's used on floors
and walls, in arc hitecture and in sculpture.
Tuff is a light porous black rock formed by
consolidation of volcanic ash. It is used as thermal
insulator and as a light weight aggregate.
Mud bricks are made of a mixt ure of clay and silt.
